基于电磁感应原理的新型发动机悬置系统的设计

The design of new engine mounting system based on electromagnetic induction principle

针对传统液压悬置存在高频振动时橡胶主簧硬化、油液泄漏等问题,在传统液压悬置的基础上,提出一种利用运动过程中线圈切割磁感线产生电流,带电导线受到磁场作用产生与运动方向相反的安培力,从而降低汽车振动和噪声的全新结构的发动机悬置系统,并对该新型悬置系统分析计算,验证其有效性。结果表明:该新型悬置系统能够有效隔离发动机振动向车内的传递,具有良好的隔振降噪效果,利于提高汽车的乘坐舒适性,为以后发动机悬置系统的设计研发提供了一种新的思路。

The traditional hydraulic mount in high-frequency vibration exists some problems such as hardened rubber main spring, oil leaks and so on. A new structure of the engine mounting system based on the traditional hydraulic mount is proposed. Influ- enced by the magnetic field ,wire with current generated by cutting magnetic induction line produce Ampere force whose direction is contrary to the direction of movement to reduce vehicle vibration and noise. The performance of new mounting system is ana- lyzed and calculated, verify its validity. The research shows that new mounting system with nice effect of sound and vibrational iso- lation can effectively isolate the transmission from the engine vibration, so that it can help to improve the car＇ s riding comfort and provide a new way of thinking the design and development of the engine mounting system.
